Pull the gate up in this defense game and make sure none of the attackers makes it through. You will be in charge of keeping the fortress secure as you are under siege from a race of barbarians. Use the cannon to shoot and hire units to fight.
Defending the building is even more intense in the sequel to Palisade Guardian. This castle defense shooting game will thrust you into the action with 6 modern weapons including an MP5, an M249 SAW, and even an RPG-7.
